Description

本発明は、円錐ころ軸受組立装置および円錐ころ軸受の組立方法に関する。   The present invention relates to a tapered roller bearing assembling apparatus and a tapered roller bearing assembling method.

従来、保持器のポケットに円錐ころを組み込む場合には、円錐ころを、円錐ころの小径側を先頭にして保持器のポケットの内側かつ周方向の幅が広い側からポケットに挿入した後、ポケットの周方向の幅が広い側に円錐ころの大径側を押し込んで、保持器のポケットに円錐ころを組み込んでいる。   Conventionally, when a tapered roller is incorporated into a cage pocket, the tapered roller is inserted into the pocket from the inside of the cage pocket and from the side having the larger circumferential width, with the smaller diameter side of the tapered roller at the top, The tapered roller is incorporated into the pocket of the cage by pushing the large diameter side of the tapered roller into the wider side in the circumferential direction.

しかしながら、この方法では、テーパ角（円錐ころの中心軸を含む断面における二つの斜辺がなす角）が大きい円錐ころをポケットに組み込む場合、円錐ころの大径側をポケットに押し込むときに、円錐ころの大径側とポケットの縁との隙間が過小になって、円錐ころの大径側が上記縁にひっかかり易くなり、円錐ころをポケットに組込にくいという問題がある。
特開２００３−１８４８９３号公報 However, in this method, when a tapered roller having a large taper angle (an angle formed by two oblique sides in the cross section including the central axis of the tapered roller) is incorporated into the pocket, the tapered roller is inserted when the large diameter side of the tapered roller is pushed into the pocket. The gap between the large-diameter side and the edge of the pocket becomes too small, and the large-diameter side of the tapered roller is easily caught on the edge, and there is a problem that it is difficult to incorporate the tapered roller into the pocket.
JP 2003-184893 A

そこで、本発明の課題は、テーパ角が大きい円錐ころであっても円錐ころを保持器のポケットに容易に組み込むことができる円錐ころ軸受組立装置および円錐ころ軸受の組立方法を提供することにある。   Accordingly, an object of the present invention is to provide a tapered roller bearing assembling apparatus and a method of assembling a tapered roller bearing that can easily incorporate a tapered roller into a pocket of a cage even if the tapered roller has a large taper angle. .

上記課題を解決するため、この発明の円錐ころを保持器に組み込む装置は、保持器のポケットにその保持器の内側から円錐ころをその円錐ころの大径側から挿入することを特徴としている。   In order to solve the above-mentioned problems, a device for incorporating a tapered roller of the present invention into a cage is characterized in that the tapered roller is inserted from the inside of the cage into the pocket of the cage from the large diameter side of the tapered roller.

円錐ころの小径側を先頭にして円錐ころを保持器のポケットに挿入する場合、保持器のポケットに円錐ころを円錐ころにおける径が最も小さい部分から挿入することになるので、円錐ころが保持器のポケットの縁にひっかかりにくくて、ポケットに円錐ころの先頭を突っ込み易くなる。一方、円錐ころの大径側を先頭にして円錐ころを保持器のポケットに挿入する場合、保持器のポケットに円錐ころを円錐ころにおける径が最も大きい部分から挿入することになるので、円錐ころが保持器のポケットの縁にひっかかり易くなって、ポケットに円錐ころの先頭を突っ込みにくくなる。このことから、今まで当業者の間において、保持器のポケットに円錐ころを円錐ころの大径側から挿入するという技術的思想は存在しなかった。しかしながら、本発明者は、先ずポケットに円錐ころの小径側の部分を突っ込む場合では、低トルク化を実現できるものとして近年注目されつつあるテーパ角（円錐ころの中心軸を含む断面における二つの斜辺がなす角）が大きい円錐ころを保持器のポケットに挿入する場合、ポケットに小径側の部分を突っ込んだ後に、円錐ころの大径側の部分を押し込むときに、この大径側の部分とポケットの縁との隙間が過小になって、円錐ころの大径部をポケットに押し込みにくくなることを発見した。そして、特に、テーパ角が８°３０′（８度３０分）を越える円錐ころを、保持器のポケットに組み込む場合においては、組込が極めて困難になることを試験的に見い出した。また、本発明者は、保持器のポケットに円錐ころを円錐ころの大径側から挿入した場合、円錐ころの大径側の部分をポケットに突っ込んだ後に、円錐ころの小径側の部分を押し込む時、小径側の部分とポケットの縁との隙間が、先ずポケットに円錐ころの小径側の部分を突っ込む場合と比して大きくなって円錐ころを保持器に組み込み易いことを発見し、テーパ角が８°３０′（８度３０分）を越える円錐ころであっても、円錐ころを、保持器のポケットに問題がなく組み込むことができることを発見した。   When the tapered roller is inserted into the cage pocket with the small diameter side of the tapered roller at the head, the tapered roller is inserted into the cage pocket from the portion with the smallest diameter in the tapered roller. It is hard to get caught in the edge of the pocket, and it becomes easier to thrust the top of the tapered roller into the pocket. On the other hand, when the tapered roller is inserted into the cage pocket with the large-diameter side of the tapered roller at the head, the tapered roller is inserted into the cage pocket from the largest diameter portion of the tapered roller. However, it becomes easy to get caught in the edge of the pocket of the cage, and it becomes difficult to push the top of the tapered roller into the pocket. For this reason, until now, there has been no technical idea among those skilled in the art to insert the tapered roller into the pocket of the cage from the large diameter side of the tapered roller. However, the present inventor has first noticed that taper angles (two hypotenuses in the cross section including the central axis of the tapered roller) can be realized when the portion on the small diameter side of the tapered roller is inserted into the pocket. When inserting a tapered roller with a large angle) into the cage pocket, push the small diameter part into the pocket and then push the large diameter part into the pocket. It was discovered that the gap with the edge of the roller became too small, making it difficult to push the large diameter part of the tapered roller into the pocket. In particular, when a tapered roller having a taper angle exceeding 8 ° 30 ′ (8 ° 30 minutes) is incorporated into the pocket of the cage, it has been found experimentally that the assembly becomes extremely difficult. Further, when the tapered roller is inserted into the cage pocket from the large diameter side of the tapered roller, the inventor pushes the small diameter side portion of the tapered roller after the large diameter side portion of the tapered roller is pushed into the pocket. It was discovered that the gap between the small-diameter portion and the edge of the pocket was larger than when the small-diameter portion of the tapered roller was first pushed into the pocket, and the tapered roller was easily incorporated into the cage. It has been discovered that even if the tapered roller exceeds 8 ° 30 ′ (8 ° 30 minutes), the tapered roller can be incorporated into the cage pocket without any problems.

本発明によれば、保持器のポケットに円錐ころを保持器の内側かつ円錐ころの大径側から挿入するので、テーパ角が大きい円錐ころであっても円錐ころを保持器に容易に組み込むことができる。   According to the present invention, since the tapered roller is inserted into the cage pocket from the inside of the cage and from the large diameter side of the tapered roller, the tapered roller can be easily incorporated into the cage even if the tapered roller has a large taper angle.

The inner ring clamp member 40 is configured to hold the inner ring 25 while restricting the position of the inner ring 25 to a position where the central axis of the inner ring 25 is located on an extension line of the central axis of the inner jig 10. . The cage stand moving device 41 and the inner ring moving device 42 are composed of a linear motor, a servo device, and the like. As described above, the retainer base moving device 41 moves the retainer base 12 in the direction of the arrow a in the axial direction of the large-diameter end portion 21, so that the retainer base 12 has the tapered roller insertion position, It is possible to move freely between the cage assembly positions. On the other hand, in the inner ring moving device 42, the end surface on the small diameter side of the inner ring 25 is the small diameter end portion 20 in the large diameter end portion 21 from the inner ring mounting position that is separated from the end surface of the small diameter end portion 20 in the normal direction of the end surface. The inner ring 25 is moved in the direction of the arrow b along the position limited by the inner ring clamp member 40 to the cage assembly position located on the side end surface.

Thus, the above structure is integrated inseparably by caulking inward in the radial direction. This caulking is performed by covering the structure with a mold and pressing the small-diameter annular portion with the mold to squeeze the small-diameter annular portion inward in the radial direction.

上記構成の円錐ころ軸受組立装置を用いて、円錐ころ軸受を以下のように組み立てる。   A tapered roller bearing is assembled as follows using the tapered roller bearing assembling apparatus having the above configuration.

先ず、円錐ころ組込工程を行う。この円錐ころ組立工程では、保持器台１２を、保持器台移動装置４１によって、上記円錐ころ挿入位置に移動させた後、大径環状部と小径環状部との間が複数の柱部で連結された構造を有する保持器３０を、その保持器３０の小径環状部が保持器台１２の載置部である上記端面に接触している状態で、クランプ部３１で保持器台１２に固定する。続いて、ガイド通路１４の小径端部２０側と反対側の開口から、円錐ころ３５をその円錐ころ３５の大径側を先頭にして、ガイド通路１４内に複数続けて挿入し、小径端部２０側の先頭の円錐ころ３５の大径側が保持器３０のポケット３３の縁部に突き当たるようにする。そして、その後、サーボモータ１３によって保持器台１２を大径端部２１に対して回転するのと同時に、小径端部２０側と反対側の最後尾の円錐ころ３５の小径側の端面を、電動シリンダ１６のロッドで所定の力で押圧することによって、円錐ころ３５を順次ポケット３３に組み付ける。すなわち、円錐ころ３５を、保持器３５の大径側を先頭にして保持器３０の内側かつ保持器３０の小径環状部側からポケット３３に挿入して、円錐ころ３５を保持器３０に組み付ける。厳密には、保持器３０の大径環状部におけるポケット３３に面する縁面部分の中心（略扇形形状の面部分の径方向および周方向の中心）の法線に対して円錐ころ３５の中心軸が鋭角をなしている状態で、保持器３０の内側かつポケット３３の周方向の幅が狭い側（保持器３０の小径環状部側）から、円錐ころ３５をその大径側を先頭にして３３ポケットに斜めに挿入して、円錐ころ３５を保持器３０に組み付ける。ここで、上記縁面部分の中心の法線に対して円錐ころ３５の中心軸が鋭角をなしている状態とは、上記縁面部分の中心の法線と円錐ころ３５の中心軸が交差していない場合も含む。この場合、上記縁面部分の中心の法線に対して円錐ころ３５の中心軸が鋭角をなしている状態とは、円錐ころ３５の中心軸を平行移動して、その中心軸を上記縁面部分の中心の法線と交差させた場合に、その平行移動した中心軸が上記縁面部分の中心の法線と鋭角をなしている状態をいう。   First, a tapered roller assembly process is performed. In this tapered roller assembling step, the cage base 12 is moved to the tapered roller insertion position by the cage stand moving device 41, and then the large-diameter annular portion and the small-diameter annular portion are connected by a plurality of column portions. The retainer 30 having the above-described structure is fixed to the retainer base 12 by the clamp portion 31 in a state where the small-diameter annular portion of the retainer 30 is in contact with the end face that is the placement portion of the retainer base 12. . Subsequently, a plurality of tapered rollers 35 are continuously inserted into the guide passage 14 from the opening opposite to the small diameter end portion 20 side of the guide passage 14 with the large diameter side of the tapered roller 35 at the head, and the small diameter end portion is inserted. The large diameter side of the leading tapered roller 35 on the 20 side is made to abut against the edge of the pocket 33 of the cage 30. Then, simultaneously with the rotation of the retainer base 12 with respect to the large diameter end portion 21 by the servomotor 13, the end surface on the small diameter side of the last tapered roller 35 opposite to the small diameter end portion 20 side is electrically driven. The tapered rollers 35 are sequentially assembled in the pocket 33 by pressing with a predetermined force with the rod of the cylinder 16. That is, the tapered roller 35 is inserted into the pocket 33 from the inside of the cage 30 and from the small-diameter annular portion side of the cage 30 with the larger diameter side of the cage 35 as the head, and the tapered roller 35 is assembled to the cage 30. Strictly speaking, the center of the tapered roller 35 with respect to the normal of the center of the edge surface portion facing the pocket 33 in the large-diameter annular portion of the cage 30 (the radial and circumferential centers of the substantially fan-shaped surface portion). In a state where the shaft forms an acute angle, the tapered roller 35 starts from the inner side of the retainer 30 and the side where the circumferential width of the pocket 33 is narrow (the smaller-diameter annular portion side of the retainer 30) with the larger-diameter side at the head. The tapered roller 35 is assembled to the cage 30 by being inserted into the 33 pockets obliquely. Here, the state in which the central axis of the tapered roller 35 forms an acute angle with respect to the normal line at the center of the edge surface portion means that the normal line at the center of the edge surface portion intersects with the central axis of the tapered roller 35. This includes cases where it is not. In this case, the state in which the central axis of the tapered roller 35 forms an acute angle with respect to the normal line of the center of the edge portion means that the central axis of the tapered roller 35 is translated and the central axis is moved to the edge surface. When intersecting with the normal at the center of the portion, the translated central axis forms an acute angle with the normal at the center of the edge portion.

次に、保持器組み付け工程を行う。この保持器組み付け工程では、内輪移動装置４２によって、内輪２５を、上記内輪装着位置から上記保持器組込位置まで、内輪クランプ部材４０によって制限されている位置に沿って移動させた後、保持器台移動装置４１によって、保持器台１２を、上記円錐ころ挿入位置から上記保持器組み付け位置まで移動させて、円錐ころ３５が組み込まれた保持器３０を内輪２５に組み付ける。   Next, a cage assembly process is performed. In this cage assembly process, the inner ring moving device 42 moves the inner ring 25 from the inner ring mounting position to the cage assembly position along the position limited by the inner ring clamp member 40, and then the cage. The cage holder 12 is moved from the tapered roller insertion position to the cage assembly position by the table moving device 41, and the cage 30 incorporating the tapered rollers 35 is assembled to the inner ring 25.

続いて、保持器かしめ工程を行う。この保持器かしめ工程では、保持器かしめ装置３によって、内輪２５に組み込まれた円錐ころ３５を保持した保持器３０の小径環状部を周方向の全周に亘って径方向の内方にかしめて、内輪２５、保持器３０および円錐ころ３５を互いに分離不可能に一体化する。   Subsequently, a cage caulking process is performed. In this cage caulking step, the cage caulking device 3 caulks the small-diameter annular portion of the cage 30 holding the tapered rollers 35 incorporated in the inner ring 25 radially inward over the entire circumference. The inner ring 25, the cage 30 and the tapered roller 35 are integrated so as not to be separated from each other.

最後に、別のポジションで、一体化された内輪２５、保持器３０および円錐ころ３５の径方向の外周側に、着脱自在の外輪（図示せず）をかぶせて、円錐ころ軸受の組立を完了する。   Finally, in another position, the removable outer ring (not shown) is put on the radially outer peripheral side of the integrated inner ring 25, cage 30 and tapered roller 35 to complete the assembly of the tapered roller bearing. To do.

課題を解決するための手段の欄で説明したように、本発明者は、円錐ころ軸受用の保持器のポケットに円錐ころを円錐ころの大径側から挿入した場合、円錐ころの大径側の部分をポケットに突っ込んだ後に、円錐ころの小径側の部分を押し込む時、小径側の部分とポケットの縁との隙間が、先ずポケットに円錐ころの小径側の部分を突っ込む場合と比して大きくなって円錐ころを保持器に組み込み易いことを発見した。そして、テーパ角が８°３０′（８度３０分）を越える円錐ころであっても、円錐ころを、保持器のポケットに問題がなく組み込むことができることを発見した。   As described in the section of the means for solving the problem, the present inventor, when the tapered roller is inserted into the pocket of the cage for the tapered roller bearing from the large diameter side of the tapered roller, When the small diameter part of the tapered roller is pushed into the pocket, the gap between the small diameter part and the edge of the pocket is first compared to the case where the small diameter part of the tapered roller is pushed into the pocket. It has been found that it becomes easy to incorporate the tapered roller into the cage. And it was discovered that even a tapered roller having a taper angle exceeding 8 ° 30 '(8 degrees 30 minutes) can be incorporated into the pocket of the cage without any problem.

上記実施形態の円錐ころ軸受組立装置によれば、保持器３０のポケット３３に円錐ころ３５を保持器３０の内側かつ円錐ころ３５の大径側から挿入するので、円錐ころ３５のテーパ角が大きい場合においても、円錐ころ３５を保持器３０に容易に組み込むことができる。   According to the tapered roller bearing assembly apparatus of the above embodiment, the tapered roller 35 is inserted into the pocket 33 of the cage 30 from the inside of the cage 30 and the large diameter side of the tapered roller 35, so the tapered angle of the tapered roller 35 is large. Even in this case, the tapered roller 35 can be easily incorporated into the cage 30.

また、上記実施形態の円錐ころ軸受組立装置によれば、円錐ころ３５をポケット３３までガイドするガイド通路１４と、円錐ころ３５をポケット３３に押圧する電動シリンダ１６とを有するので、円錐ころ３５を、ガイド通路１４を通じて保持器３０のポケット３３まで円滑に移動させることができて、保持器３０のポケット３３に円錐ころ３５の大径側を容易に挿入できる。   Further, according to the tapered roller bearing assembly apparatus of the above embodiment, the tapered roller 35 is provided with the guide passage 14 that guides the tapered roller 35 to the pocket 33 and the electric cylinder 16 that presses the tapered roller 35 against the pocket 33. The guide roller 14 can be smoothly moved to the pocket 33 of the cage 30, and the large diameter side of the tapered roller 35 can be easily inserted into the pocket 33 of the cage 30.

また、上記実施形態の円錐ころ軸受組立装置によれば、サーボモータ１３で保持器台１２を大径端部２１に対して回転させることによって、貫通穴２２の円錐ころ押し出し口に対して保持器３０のポケット３３を回動させることができる。したがって、保持器３０の周方向に所定間隔毎に形成されている複数のポケット３３に、円錐ころ３５を順次自動的かつ迅速に組み込むことができる。   Further, according to the tapered roller bearing assembly apparatus of the above embodiment, the cage is rotated with respect to the tapered roller extrusion port of the through hole 22 by rotating the cage base 12 with respect to the large diameter end portion 21 by the servo motor 13. Thirty pockets 33 can be rotated. Accordingly, the tapered rollers 35 can be sequentially and automatically incorporated into the plurality of pockets 33 formed at predetermined intervals in the circumferential direction of the cage 30.

また、上記実施形態の円錐ころ軸受組立装置によれば、小径軸部２０に内輪２５を位置決めして保持することができ、また、上記小径軸部２０が内輪２５を保持している状態で、保持器台移動装置４１で保持器台１２を内輪２５側に移動させることによって、保持器３０を内輪２５に組み付けることができる。また、上記保持器かしめ装置３によって、内輪２５に組み付けられた保持器３０をかしめることによって、円錐ころ３５、保持器３０および内輪２５を一体にできる。   Further, according to the tapered roller bearing assembly device of the above embodiment, the inner ring 25 can be positioned and held on the small diameter shaft portion 20, and the small diameter shaft portion 20 holds the inner ring 25. The cage 30 can be assembled to the inner ring 25 by moving the cage stage 12 toward the inner ring 25 with the cage stage moving device 41. Further, the cage roller 35, the cage 30 and the inner ring 25 can be integrated by caulking the cage 30 assembled to the inner ring 25 by the cage caulking device 3.

また、上記実施形態の円錐ころ軸受の組立方法によれば、保持器３０のポケット３３に円錐ころ３５を保持器３０の内側かつ円錐ころ３５の大径側から挿入するので、円錐ころ３５のテーパ角が大きい場合であっても、円錐ころ３５を保持器３０に容易に組み込むことができる。   Further, according to the method of assembling the tapered roller bearing of the above embodiment, the tapered roller 35 is inserted into the pocket 33 of the cage 30 from the inside of the cage 30 and from the large diameter side of the tapered roller 35, so that the tapered roller 35 is tapered. Even when the angle is large, the tapered roller 35 can be easily incorporated into the cage 30.

As long as the retainer base is rotating with respect to the inner jig and a constant force is continuously applied to the tapered rollers by the pressing device, the tapered rollers can be sequentially incorporated into the pockets. Note that a stepping motor or the like that rotates every predetermined angle (corresponding to the angle of the adjacent pocket) can also be used as the rotating device. In this case, the tapered roller is pressed by the pressing device in a state where the opening on the pocket side of the guide passage corresponds to the pocket. In addition, as a rotation apparatus, you may use the apparatus etc. which have a gear and a toothed belt, and rotate a holder stand, for example.
